breadpad: capture the reminder window + its snooze popover

Two more views: "reminder" (the alert window from run_reminder_window,
normally only reachable via a real due note through `fire <id>`) and
"reminder-snooze" (same window, snooze popover open).

Screenshot mode builds a throwaway sample Note directly instead of going
through cmd_fire's Store lookup — main() checks for these two view names
before ever reaching run_popup's dispatch, since the reminder window is
a completely separate GApplication entry point, not reachable through
the compose-popup path screenshot mode already covered.

Same NON_UNIQUE-on-screenshot-mode fix as run_popup already had, applied
to the reminder window's own Application builder.
